Refrigeration dryers of the DFLM series are designed for drying compressed air flows up to 14 bar(g) to pressure dew points up to +3°C for compressed air without aggressive substances.

All the models are provided with an electronic condensate drain and a potential free alarm contact as stand-ard. The refrigeration dryers comply with the requirements of the Pressure Equipment Directive 97/23/EC as well as with the Machinery Directive 2006/42/EC and have the corresponding CE marking.

The air-to-air heat exchanger, the evaporator and the demister condensate separator made from aluminium are comprised in one module. This results in a compact, rugged and energy-saving design. The cooling registers are designed such that the condensate is discharged on the entire cooling path (in conventional refrigeration dryers the condensate is only discharged at the end of the cooling circuit). The generously designed air circuit causes low flow velocities and therefore results in very good condensate separation and very low pressure losses.

On DFLM132-370 are hermetic compressors, and on DFLM 462-1140 are scroll compressors used for compressing the refrigerant. They are extremely rugged and able to tolerate liquid refrigerant returns. This elimi-nates the need for pre-heating when starting the system. Compared to piston compressors scroll compressors provide lower vibration, longer service life and lower energy requirement.
